IMPROVEMENT IN APPARATUS FOR RAISING WATER BY PNEUMATIC PRESSURE.

Specification forming part of Letters Patent No. 158,676, dated J anuary 12, 1875; application filed November 19, 1874.

To all whom it may concern:

Be it known that I, RoBEnT A. UHEsE- BROUGH, of New York, inthe county and State of New York, have invented a new andu'seful Improvement in Apparatus for Raising Water by Pneumatic Pressure; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawing forming part of this specification.

My invention relates to an improvement whereby water may be supplied from a well or other source to an upper story of a building, or otherelevated position, by means of power derived from a wind-wheel and communicated' toan air-compressing apparatus and an air-reservoir.

:The object of the invention is to obtain a continuous action of the apparatus by simple automatic means without manipulation or at-.

tention. To this end one or more stationary water-receivers are placed in the well, andconnected, by a pipe or pipes, with a compressed air-reservoir, which is kept filled with compressedair by means of the air-compression pump or pumps driven by the wind-wheel, and an air cook or valve is used for alternately admitting and shutting on the compressed air to and from the said receiver or receivers for the alternate discharge and replenishment of their water; and the improvement consists in the combination of the said cook or valve with the shaft of the wind-wheel, whereby thefsaid cock or valve is operated by the said sha t.

In the accompanying drawing, Figure 1 isa side view of my improved apparatus. Fig. 2 is an end elevation. Fig. 3 is a detail sectional view.

. A represents a reservoir for compressed air,

in any suitable manner. 0n the shaft (3 is a pinion, E, by which motion is communicated, through a wheel, F, and pinion F on a shaft, f, to a gear-wheel, G, 011 a shaft, g,

all of said shafts having their bearings in the frame-work d. On one side of the wheel G is a pin or wiper, h, which e'ngageswith the two branches J J of .a forked lever, which has its fulcrum on,-and is attached to, the plug of a four-way cock, L, or other cook or valve of suitable construction, having its seat at the point of junction of three pipes, K K K (See enlarged view, Fig. 3.) The pipe 'K leads outward from the air-reservoir A provided with valves opening upward, so that the water may enter when not prevented by the presence of compressed air therein, and

with pipes leading to a water-tank located at the desired. point, through which pipes the water may be forced and conveyed to said tank.

v If desired, a single receiver, one air-pipe, and a two-way cock may be used, instead of .the two receivers and pipes above described, so

that the water maybe supplied intermittently from one receiver. I p

The air-pump is operated by the crank on the shaft 0, which is turned by means of the windwheel D. The revolution of the shaft 0 also gives motion to the gearing, as before described. As the wheel G revolves the wiper h engages alternately with the branches 1 J z of theforked lever attached to the air-cock L, and thus alternately opens and cuts off communication between the pipe K and the pipes K K, so that while one of the receivers is being charged with compressed air from the airreservoir A through the pipe K the other receiver is discharging water through its discharge-pipe to the water-tank by the operation of the compressed air in said receiver. The gearing is so calculated, with reference to the relation between the operation of the air-pump and the receivers, as to regulate the quantity of air supplied to-said receivers, and the wiper,

by being allowed to discharge into the atmosphere through the exhaust-port of the valve L, which acts doubly for both receivers.

What Iclaim as new, and desire to secure by Letters Patent, is-

In an apparatus for raising water by pneu maticpressure obtained by an air pump or compressor worked by a windmill, the combinationof the valve for supplying and shutting :ofl' the air to and from the water. receiver or receivers with the shaft of the windmill by connecting mechanism, the whole constructed to operate substantially asherein described.
